4 Claims. (Cl. 16-175) The present invention relates to hinge or hearing devices for inclining windows pivotal about a horizontal axis.

The present application is a division from my copending prior application Serial No. 662,289 filed May 28, 1957, now Patent No. 2,885,745 issued May 12, 1959.

An object of the present invention is to provide a hinge or hearing device of a simple and efficient construction which, when mounted on the window frame, will present an outer plane surface which is of importance particularly when the window frame with the hinge device is to be covered with protecting sheets.

Another object of the present invention is to provide a hinge or bearing device which will facilitate the installation of the window sash in the window frame and also the removal of the sash from the frame without removal of any part of the hinge or bearing device from window or frame.

Other objects and advantages of the invention will be obvious from the following description with reference to the accompanying drawings.

FIG. 1 is a perspective fragmentary view showing the window sash in open position and the hinge device in a position during the installation or removal of the sash.

FIG. 2 is a perspective fragmentary view showing in full lines the hinge device in its normal operative position and the sash in closed position shown by dot and dashed lines and the sash in open position shown by dashed lines.

FIG. 3 is a plan view of the covering bar or plate and FIG. 4 is a plan view of the bearing bar or plate.

FIGS. 5 and 6 are plan and side views respectively of a plate or member to be attached to the window sash and carrying the pivot.

FIG. 7 is a diagrammatical side view of a window frame and a window sash connected thereto by means of the present hinge device.

And FIG. 8 is a plan view, reduced size, of a Window incorporating the present invention.

The hinge device of the present invention is designed to be used particularly for inclining windows such as roofwindows. On the outer side of each side piece 1 of the window sash there is attached a member in the form of a plate 2 provided with holes 21 for screws and carrying a horizontal pivot 3 and a shorter projection or stop memher 4 at some distance from the pivot. On the upper side of each of the inclining side pieces 5 of the window frame a bearing bar or plate 6 is attached, said plate having holes 22 (FIG. 4) for retaining screws. One end of this plate is bent down towards the side piece 5 to form a downwardly extending bearing yoke 7 for the pivot 3 the opening of said yoke being directed upwards. In the installation or removal of the sash the pivot 3 is movable through said opening to the bottom of the yoke and vice versa, the bottom portion of the yoke forming a semicylindrical bearing surface for the pivot.

The bearing plate at its edge adjacent to the sash is provided with a recess 8 located at the same distance from the pivot 3 or the axis of the semi-cylindrical bottom of the yoke 7 as the projection 4 so that, after swinging the sash a certain angle from its closed position, the projection 4 enters into the recess 8. On each bearing plate 6 a plane covering bar or plate 9 is provided,

ice

the plate 9 in its normal operative position covering the opening of the bearing yoke 7 and also the recess 8 in the edge of the bearing plate 6. In this position, shown in FIG. 2, the pivot 3 cannot be moved out of the bearing yoke 7, and the projection or stop member 4 cannot be moved through the recess 8 because this is prevented by the covering plate 9. This covering plate is provided with a recess 10 corresponding to the recess 8, the recess 10 being so located that when the covering plate has been moved from its nOrmal operative positionto a position in which the opening of the bearing yoke 7 is free, the recess 10 of the covering plate 9 will be right before'the recess 8 of the bearing plate 6 as shown by FIG. 1, in which position the sash, after being swung through a certain angle from closed position, can be removed from the window frame in which movement the projection 4 of the plate 2 passes through the registering recesses 8, 10.

The covering plate is attached to the bearing plate by means of two (or more) screws 11 projecting through slots 12 extending in the longitudinal direction of the covering plate 9 and engaging with holes 13 in the bearing plate 6. When these screws have been unscrewed so far that their heads are free from the countersunk portions 14 of the slots 12 but the screws are still engaging with the threads of the holes 13, so that they loosely connect the covering plate with the bearing plate, the covering plate, while being connected with the bearing plate, is slidable in its longitudinal direction so far that the opening of the bearing yoke will be uncovered and the recesses 8, 10 are right before each other. Thus the covering plates 9 may be connected with the bearing plates 6 during installation and removal of the sash.

As shown by FIGS. 2 and 7 the plates 6 and 9 are countersunk in the sidepiece 5 and owing to the upper plane surface of the covering plate 9 it is possible to mount the hinge device in such a manner that the upper face thereof will be disposed in the same plane as the upper face of the frame 5. Thus when covering the frame with a protecting sheet it will not be necessary to form said sheet with any bent or curved portion to receive the hinge device but also said sheet will present an entirely plane surface.

What I claim is:

1. A hinge device for one side of a separable inclining window with a sash adapted to be pivoted in a frame about a horizontal axis, comprising a plate capable of being attached to one of two opposite side pieces of the sash, a pivot extending from said plate for constituting one side of said axis, a bearing plate having two opposite fiat surfaces and being capable of connection to said frame adjacent said pivot with one fiat surface on said frame, said bearing plate having a portion providing a single open side bearing yoke in its other flat surface with said pivot extending therein whereby said bearing plate yoke open side in its operative position will face outwardly of said frame for the introduction and removal of its corresponding pivot therethrough, a plane covering plate positioned on said bearing plate and having two opposite flat surfaces with one surface normally covering its corresponding bearing plate yoke retaining its pivot therein and detachable means for connecting said covering plate to its bearing plate in said yoke covering position.

2. A hinge device as claimed in claim 1, wherein said bearing plate is bent at one end portion forming its hearing yoke.

3. A hinge device as claimed in claim 1, wherein said detachable means is provided by said bearing plate having at least one threaded hole, said covering plate having at least one slot therethrough and a screw extending through said covering plate slot and being in threaded engagement with said bearing plate threaded opening for 3 retaining said covering plate in position when said screw is tightenedand permitting the sliding of said covering plate on said bearing plate when said screw is loose.

4. A hinge device as claimed in claim 1, wherein said bearing plate and covering plate has an oblong shape and said covering plate 'is slideable on said bearing plate in the long'tudinal direction of said plate, said bearing plate having a slot'open in one longitudinal edge thereof, said covering plate having a slot positioned for alignment with and exposing its bearing plate slot only when said covering' plate is' slidfmm its yoke covering position and a stop" extending from said first-mentioned plate is spaced 4 from said pivot and positioned for entering through said aligned slots when said sash is pivoted in line with said frame and retained therein when said covering plate is slid to its yoke covering position retaining said sash and frame in alignment.
